Summary:                    implementation of new CHECK_C_INLINE macro
Description: 
I've implemented a CHECK_C_INLINE macro that detects what keyword, if any, is
used for inlining C functions.  The check is very similar to autoconf's
AC_C_INLINE portability macro, testing various methods to find one that works. 
The macro takes a variable from the caller and utilizes caching so tests are
only run when necessary.

Steps to Reproduce: 
# using the new macro looks like this:

CHECK_C_INLINE(C_INLINE)                                                        
                                                                                
                                    
if(NOT C_INLINE STREQUAL "inline")                                              
                                                                                
                                    
  add_definitions("-Dinline=${C_INLINE}")                                       
                                                                                
                                    
endif(NOT C_INLINE STREQUAL "inline")                                           
                                                                                
                                    

That has the convenient behavior of renaming instances of "inline" to an
alternate available keyword or to nothing/empty if none are supported.


Additional Information: 
This is a work-in-progress, but I'll be happy to maintain the macro if need be. 
A quick search indicates such a macro would be of general use suitable for
inclusion as a new built-in macro.  Constructive feedback is always welcome, of
course.
